Description

TECHNICAL FIELD

[0001] The application relates to the technical field of heat accumulating oxidation devices, in particular to an intelligent heat accumulating oxidation device capable of reducing carbon emission by recycling waste heat. BACKGROUND

[0002] The existing device for oxidizing waste gas often does not effectively utilize the waste heat generated after combustion of the waste gas, directly discharges the heat to the outside or only roughly recycles the heat, and the utilization rate of the waste heat is low in general, and the environmental protection performance is poor.

[0003] The defects existing in the prior art include but are not limited to: 1. The existing device cannot effectively utilize the waste heat after oxidation treatment of the waste gas, and the utilization rate of the waste heat is low; 2.

In theory, the higher the temperature of the heat accumulating ceramic bed after absorbing the waste heat of the waste gas, the better the preheating effect on the new waste gas, but if the temperature of the heat accumulating ceramic bed continuously accumulates and increases, the highest tolerance value of the heat accumulating ceramic bed may be exceeded, and the heat accumulating ceramic bed is damaged.

[0017] Beneficial effects:

[0018] 1. The intelligent regenerative thermal oxidation device for reducing carbon emissions by utilizing waste heat recovery provided by the present invention has a first ceramic regenerative thermal bed and a second ceramic regenerative thermal bed built in. The waste gas to be treated is preheated from one of the ceramic regenerative thermal beds and then heated to the other ceramic regenerative thermal bed after combustion treatment. Then, it is preheated from the latter and heated to the former. This process is repeated to effectively improve the overall waste heat utilization rate.

[0019] 2. The intelligent regenerative thermal oxidation device for reducing carbon emissions by utilizing waste heat recovery provided by the present invention includes an outer frame and related structures. After the waste gas is preheated and flows out from a ceramic regenerative bed, the ceramic regenerative bed can be back-purged. At this time, the waste gas will move forward for combustion and oxidation. Therefore, there is no need to spend extra time on back-purge, which effectively improves the efficiency of waste gas treatment.

[0020] 3. The intelligent regenerative thermal oxidation device for reducing carbon emissions by utilizing waste heat recovery provided by this invention has two sources of gas in the outer frame: either it can be the collection of preheated waste gas, i.e., the extraction of high-temperature gas, or it can be the extraction of gas from the outside through a normal-temperature gas inlet pipe, i.e., the storage of lower-temperature gas. If the temperature of the ceramic regenerative bed does not exceed the maximum tolerance value after absorbing waste heat, the ceramic regenerative bed can be backwashed with high-temperature gas. Conversely, if the temperature of the ceramic regenerative bed exceeds the maximum tolerance value after absorbing waste heat, the ceramic regenerative bed can be backwashed with external normal-temperature gas, i.e., relatively low-temperature gas, thereby effectively protecting the ceramic regenerative bed and making the device more durable as a whole.

[0021] This invention provides an intelligent regenerative thermal oxidation device that utilizes waste heat recovery to reduce carbon emissions. It has a high waste heat utilization rate, and backwashing does not occupy normal processing time, effectively improving the efficiency of waste gas treatment. Furthermore, it can utilize backwashing gases of different temperatures to effectively protect the ceramic regenerative bed and prevent damage to the ceramic regenerative bed due to exceeding its temperature tolerance value.

[0028] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0029] This invention provides a technical solution:

[0030] An intelligent regenerative thermal oxidation device for reducing carbon emissions by utilizing waste heat recovery includes a shell 1. A first heat insulation plate 2 and a second heat insulation plate 3 are fixedly installed inside the shell 1. Both the first heat insulation plate 2 and the second heat insulation plate 3 prevent heat exchange and mixing between the two sides. Vertical isolation blocks 4 are symmetrically fixed below both the first heat insulation plate 2 and the second heat insulation plate 3. The vertical isolation block 4 located below the first heat insulation plate 2 is fixed to a first ceramic regenerative bed 5, and the vertical isolation block 4 located below the second heat insulation plate 3 is fixed to a second ceramic regenerative bed 6. The first ceramic regenerative bed 5 and the second ceramic regenerative bed 6 have the same structure and both have ventilation holes 601 for easy monitoring. The first ceramic regenerator bed 5 and the second ceramic regenerator bed 6 are fixed to the inner wall of the shell 1 on both sides by transverse isolation blocks 7. The first ceramic regenerator bed 5 and the inner wall of the shell 1 are separated by the longitudinal isolation block 4 and the transverse isolation block 7 located below, thus forming the first chamber 801 and the second chamber 802. The second ceramic regenerator bed 6 and the inner wall of the shell 1 are separated by the longitudinal isolation block 4 and the transverse isolation block 7 located above, thus forming the third chamber 901 and the fourth chamber 902. The first chamber 801, the second chamber 802, the third chamber 901 and the fourth chamber 902 are independent of each other.

[0031] The first chamber 801 is connected to the first air duct 11 and the second air duct 12. The first air duct 11 is equipped with valve 111, and the second air duct 12 is equipped with valve 121. The third chamber 901 is connected to the third air duct 13 and the fourth air duct 14. The third air duct 13 is equipped with valve 131, and the fourth air duct 14 is equipped with valve 141. The first air duct 11, the second air duct 12, the third air duct 13, and the fourth air duct 14 are all dual-purpose pipes, which can both supply and exhaust air. The first chamber 801 and the third chamber 901 are both equipped with dust storage devices to store the dust blown off from the first ceramic regenerator bed 5 and the second ceramic regenerator bed 6 by backflushing.

[0032] Both the second chamber 802 and the fourth chamber 902 are connected to the inner cavity enclosed by the outer frame 20. Both outer frames 20 are fixedly mounted on the housing 1. A hydraulic cylinder 21 is fixedly mounted on the inner wall of the outer frame 20 away from the housing 1. A push plate 22 is fixedly mounted on the output end of the hydraulic cylinder 21. The push plate 22 can move against the inner wall of the outer frame 20. A mounting plate 23 is fixedly mounted in the outer frame 20. Multiple air-concentrating hoods 24 are fixedly embedded in the mounting plate 23. The inner diameter of the air-concentrating hood 24 at the end away from the hydraulic cylinder 21 is smaller than that at the other end. Therefore, the air pressure of the gas blown out from the air-concentrating hood 24 will increase, thereby increasing the mixing force of the air and allowing the airflow to travel further. An extended housing 201 is integrally formed at the bottom of the outer frame 20. The extended housing 201 contains... The device includes a first cylinder 25 and a second cylinder 26. The output end of the first cylinder 25 is fixedly equipped with an air distribution plate 27, which has an air distribution hole 271. The output end of the second cylinder 26 is fixedly equipped with an isolation plate 28, which can completely isolate the second chamber 802 and the fourth chamber 902 from the inner cavity of the outer frame 20. The bottom of the outer frame 20 is connected to a normal temperature air inlet pipe 29, which is equipped with a valve 291. The side walls of the first ceramic heat storage bed 5 and the second ceramic heat storage bed 6 are both attached with concave blocks 31. The inner top wall of the concave block 31 is fixedly equipped with a switch 32 and a connecting spring 33. The connecting spring 33 is connected to a trigger plate 34, which can be lifted by a high temperature deformation device to trigger the switch 32.

[0033] A combustion chamber 36 is formed between the second heat insulation plate 3 and the inner cavity top wall of the shell 1 for exhaust gas combustion. An ignition combustion device is provided in the combustion chamber 36. A first guide pipe 37 is provided between the combustion chamber 36 and the second chamber 802. A valve 371 is provided on the first guide pipe 37. A second guide pipe 38 is provided between the combustion chamber 36 and the fourth chamber 902. A valve 381 is provided on the second guide pipe.

[0034] Furthermore, a support leg 101 is fixedly provided at the bottom of the housing 1.

[0035] Furthermore, the dust storage device includes a dust collection box 16, which is used to collect dust blown out from the ventilation holes 601 of the first ceramic regenerator bed 5 or the second ceramic regenerator bed 6. The dust collection box 16 is provided with a dust inlet hole 161. A filter screen plate 162 is embedded in the side wall of the dust collection box 16 away from the dust inlet hole 161. The filter screen plate 162 allows gas to flow and be discharged from the dust collection box 16, but dust will not be blown out to avoid environmental pollution. Each dust inlet hole 161 is connected to a dust inlet pipe 15. The two dust inlet pipes 15 are respectively connected to the first chamber 801 and the third chamber 901. Each dust inlet pipe 15 is provided with a valve 151, which can be opened or closed as needed.

[0036] Furthermore, a fixing block 17 is fixedly installed on the top wall of the inner cavity of the dust collection box 16, and a baffle 18 is hinged on the fixing block 17. The baffle 18 can rotate, and a return spring 19 is connected between the baffle 18 and the inner wall of the dust collection box 16. When there is no wind, the baffle 18 is pushed up by the return spring 19, thereby isolating the dust inlet hole 161 from the bottom inner cavity of the dust collection box 16, thus preventing the dust in the inner cavity of the dust collection box 16 from flowing back and causing secondary pollution.

[0037] Furthermore, the air distribution holes 271 are multiple and evenly spaced on the air distribution plate 27, so the blown air is more uniform and the mixing effect is better, effectively avoiding the problem of excessive differences between local areas.

[0038] Furthermore, temperature sensors 30 are attached to the side walls of both the first ceramic heat storage bed 5 and the second ceramic heat storage bed 6 to determine whether the first ceramic heat storage bed 5 or the second ceramic heat storage bed 6 is overheated.

[0039] Furthermore, there are two sets of connecting springs 33, which are symmetrically arranged on both sides of the switch 32, so the trigger plate 34 is subjected to more even and stable force when it moves.

[0040] Furthermore, the high-temperature deformation device is a thermosensitive expansion joint 35. If the temperature rises, the thermosensitive expansion joint 35 will deform and rise upwards. Since the thermosensitive expansion joint 35 is a commonly used structure in heat exchangers, the existing technology is already very mature, so it will not be described in detail here.

[0041] Furthermore, the ignition and combustion device includes a burner 39, which is fixedly installed on the outer wall of the housing 1. A manifold 40 is connected to the burner 39 and is fixedly installed on the top wall of the inner cavity of the housing 1. Multiple combustion nozzles 41 are connected to the bottom of the manifold 40, and open flames can be ejected from the combustion nozzles 41 to burn the exhaust gas.

[0042] Example 1:

[0043] In operation, this device operates in two separate cycles of air intake and exhaust from different directions. During the first cycle, valves 111, 371, 381, and 131 are all open, while the other valves are closed. The ambient temperature exhaust gas enters the first chamber 801 through the first duct 11, then passes through the ventilation holes 601 in the higher-temperature first ceramic regenerator bed 5 for preheating. Afterward, it enters the second chamber 802 and then flows through the first guide pipe 37 into the combustion chamber 36. At this point, the combustion... An open flame will be ejected from the burner 41 to burn the exhaust gas. After the exhaust gas is treated, the temperature is high. The high-temperature gas then enters the fourth chamber 902 through the second guide pipe 38 and enters the third chamber 901 through the ventilation hole 601 on the second ceramic heat storage bed 6. During this process, the second ceramic heat storage bed 6 absorbs the waste heat of the high-temperature gas, effectively improving the utilization rate of waste heat, reducing carbon emissions, and making it more green and environmentally friendly. Finally, the gas in the fourth chamber 902 after the waste heat has been absorbed is discharged from the shell 1 through the third air duct 13.

[0044] In the second treatment, valves 141, 381, 371, and 121 are all opened, while the other valves in the device are closed. The ambient temperature exhaust gas enters the third chamber 901 through the fourth duct 14, and then passes through the ventilation hole 601 in the second ceramic regenerator bed 6, which was heated in the previous treatment, to achieve preheating. After that, it enters the fourth chamber 902 and then enters the combustion chamber 36 through the second guide pipe 38. At this time, the combustion nozzle 41 will spray open flames to burn the exhaust gas. After the treated exhaust gas has a high temperature, the high temperature gas enters the second chamber 802 through the first guide pipe 37 and enters the first chamber 801 through the ventilation hole 601 on the first ceramic regenerator bed 5. During this process, the first ceramic regenerator bed 5 absorbs the residual heat of the high temperature gas. Finally, the gas in the first chamber 801 that has absorbed the residual heat is discharged from the shell 1 through the second duct 12.

[0045] Therefore, by performing cyclical operations according to the first and second treatment routes described above, the first ceramic regenerator bed 5 and the second ceramic regenerator bed 6 can be used sequentially as carriers for absorbing waste heat and releasing heat. The waste heat generated in the previous cycle can be quickly absorbed by the waste gas to be treated in the next cycle, avoiding delays that could lead to heat dissipation. This not only makes full use of the waste heat generated after the combustion of the waste gas, but also, during the cyclic intake-exhaust process, airflows from different directions will alternately blow onto the first ceramic regenerator bed 5 and the second ceramic regenerator bed 6, avoiding the drawback of the ventilation holes 601 in the first ceramic regenerator bed 5 and the second ceramic regenerator bed 6 being blocked.

[0046] Example 2:

[0047] During the use of Embodiment 1, the ventilation holes 601 of the first ceramic heat storage bed 5 or the second ceramic heat storage bed 6 can be back-blown periodically. This can be divided into two situations: the temperature of the first ceramic heat storage bed 5 or the second ceramic heat storage bed 6 itself has not exceeded or has exceeded the maximum tolerance value. In this embodiment, the temperature has not exceeded the maximum tolerance value.

[0048] Specifically, taking the first treatment in Embodiment 1 as an example, when the exhaust gas is blown into the second chamber 802 through the first ceramic regenerator bed 5, the first cylinder 25 and the second cylinder 26 simultaneously contract downwards, the hydraulic cylinder 21 contracts and drives the push plate 22 to move, thereby drawing the preheated gas into the inner cavity of the outer frame 20. Then, the second cylinder 26 is activated in reverse, causing the second cylinder 26 to drive the isolation plate 28 upwards, thereby isolating the second chamber 802 from the inner cavity of the outer frame 20, until all the exhaust gas from this treatment enters the first guide pipe 37, i.e. Valve 371 can be closed, and then the second cylinder 26 can be started. As the second cylinder 26 moves the isolation plate 28 downward, the hydraulic cylinder 21 quickly pushes the push plate 22 outward, causing the previously extracted high-temperature gas to be ejected from the wind shroud 24. At this time, the pressure and intensity of the airflow are increased, and the range is longer, which can effectively back-purge the ventilation holes 601 in the first ceramic regenerator bed 5. The back-purge of the second ceramic regenerator bed 6 is similar to the above process, and will not be described in detail here. The above operation can be implemented by an external PLC controller, which is more convenient to use.

[0049] Example 3:

[0050] During the use of Embodiment 1, the ventilation holes 601 of the first ceramic heat storage bed 5 or the second ceramic heat storage bed 6 can be back-blown periodically. This can be divided into two situations: the temperature of the first ceramic heat storage bed 5 or the second ceramic heat storage bed 6 itself has not exceeded or has exceeded the maximum tolerance value. In this embodiment, the temperature has exceeded the maximum tolerance value.

[0051] Specifically, taking the first treatment in Embodiment 1 as an example, when the exhaust gas is blown into the second chamber 802 through the first ceramic regenerator bed 5, the isolation plate 28 is in a state of isolating the second chamber 802 from the inner cavity of the outer frame 20. If the gas temperature in the second chamber 802 is too high, the thermal expansion joint 35 will expand due to heat, thereby pushing the trigger plate 34 upward. The trigger plate 34 moves upward and triggers the switch 32. At this time, the first cylinder 25 starts and pushes the air distribution plate 27 upward until the top of the air distribution plate 27 contacts the inner wall of the outer frame 20 and stops. Then, after all the exhaust gas in this treatment has entered the first guide pipe 37, the valve 371 can be closed and the valve 291 can be opened, causing the hydraulic cylinder 21 to contract and drive the push plate 22 to move, attracting the gas with a lower temperature in the external environment to the outer frame. Inside the cavity of body 20, valve 291 is closed, and the second cylinder 26 drives the isolation plate 28 downward, causing the hydraulic cylinder 21 to quickly push the push plate 22 outward. This causes the extracted relatively low-temperature gas, i.e., the room-temperature gas in the external environment, to be sprayed out from the wind shroud 24. After passing through the air distribution holes 271 on the air distribution plate 27, it is blown towards the ventilation holes 601 in the first ceramic heat storage bed 5. While back-flushing the first ceramic heat storage bed 5, it also cools down the first ceramic heat storage bed 5, preventing the temperature of the first ceramic heat storage bed 5 from exceeding the maximum tolerance value due to heat accumulation, which could easily lead to damage. This effectively protects the first ceramic heat storage bed 5 and the second ceramic heat storage bed 6. The back-flushing of the second ceramic heat storage bed 6 is similar to the above process and will not be described in detail here. The above operation can be implemented by an external PLC controller, which is more convenient to use.

[0052] Example 4:

[0053] During the operation of Embodiments 2 and 3 above, valve 5151 at the corresponding position can be opened. At this time, the airflow blows towards the baffle 18 after passing through the dust inlet pipe 15. The baffle 18 presses down the reset spring 19 and opens, allowing the airflow carrying dust to enter the inner cavity of the dust collection box 16. Excess gas is discharged to the outside from the filter plate 162, while the dust is stored at the bottom of the dust collection box 16. When the blowing airflow stops, the baffle 18 is lifted and reset by the action of the reset spring 19. At this time, the dust inlet hole 161 and the bottom inner cavity of the dust collection box 16 are isolated from each other, thereby preventing the dust in the inner cavity of the dust collection box 16 from flowing out in reverse and causing secondary pollution.

[0054] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
